Summary: | An image processing method includes the operations of receiving N×N raw data from an N×N sub pixel array including a plurality of first exposure pixels and second exposure pixels having different exposure times, respectively; obtaining a difference value between a value obtained by normalizing an interpolated value of the first exposure pixels and an interpolated value of the second exposure pixels for each channel in the N×N sub pixel array based on the N×N raw data; setting a mismatching value to a maximum value among difference values obtained for the respective channels; and setting a corrected value of a central pixel in the N×N sub pixel array based on the N×N raw data and based on the mismatching value and a threshold value. |
